Enhancing interaction with the driving ecology through haptic interfaces

Technology developments in the areas of sensors, controllers, wireless communication, and low-cost computers will dramatically change driving in the coming years. Concerns about distraction due to a wide array of in-vehicle information systems (e.g., voice-based email systems) coupled with an increasing degree of automatic vehicle control systems (e.g., adaptive cruise control) present important design challenges. This technology may distance drivers from the driving situation and may delay their responses to unanticipated, high-demand situations. One way to address this issue is to provide the driver with additional information and warnings; however, additional auditory information may be annoying and visual displays may be distracting. Haptic interfaces offer a promising alternative. This paper describes how techniques adapted from Ecological Interface Design might help identify how different types of haptic interfaces might best convey driving-related information.
